Building an AR-15 from a stripped lower receiver doesn't have to mean hunting through catalogs for individual springs, pins, and detents. The Aero Precision EPC Lower Parts Kit with MOE Grip is purpose-built to simplify the assembly process—it includes every component you need to finish your EPC lower receiver and nothing you don't. This kit pairs Aero's engineering with Magpul's ergonomic MOE grip, giving you a cohesive, reliable platform whether you're assembling a precision rifle, competition gun, or dependable home-defense build.

Aero Precision has engineered their EPC (Enhanced Precision Caliber) platform to accept standard AR-15 compatible parts, which means this lower parts kit works seamlessly with EPC lower receivers while maintaining full compatibility with modern AR infrastructure. The kit includes all the springs, detents, pins, and controls needed—takedown and pivot pins, bolt catch assembly, safety selector, trigger and hammer springs, disconnector, and more. The hardened trigger and hammer pins ensure durability through thousands of rounds, and the included 4-40 set screw accommodates threaded takedown pin detent holes for builders who want a slick, screw-retained design.

The Magpul MOE grip bundled in this kit is a proven favorite among AR builders—it's comfortable, texturally grippy, and dimensioned for both shooting and manipulation. Aero includes the grip screw, so you're ready to install it straight out of the box. Whether you're a first-time lower receiver builder or a seasoned gunsmith stocking up on complete kits, this all-in-one approach saves time, eliminates the guesswork of sourcing compatible components, and gives you confidence that every part works together as intended.
